I'm not having this bug but stumbled on it when helping someone else, I haven't got time to read through all this, but I managed to get this error when playing with my own alsamixer (even thou my sound is working fine)
alsamixer -D hw:0 <- works as it should
alsamixer -D hw:1
alsamixer: function snd_ctl_open failed for hw:1: No such file or directory
perhaps there's just problems for some ppl trying to open a mixer for a non existent sound card.. where the defoult is stored I have no idea :) just thought it might help someone
